Abstract: To more effectively remove contaminants from fluid streams, several types of metal precursors can be incorporated onto highly ordered mesoporous molecular sieves, such as SBA-15, without producing of clogging effects within pore structures. Lanthanum and aluminum are the most favorable incorporated metals in terms of their adsorption capacities and fluid velocities. The lanthanum impregnated SBA-15 also has a very strong selectivity for arsenic because its adsorption capacities do not deteriorate even if several other anionic species, such as sulfate and nitrate, are found in high concentrations in the fluid along with any arsenic. As a result, these hybrid materials have many advantages for use in POE/POU applications, among others, due to its rapid and high adsorption capacity, and its high selectivity of arsenic for removal from the fluid stream.

Abstract translation: 为了更有效地从流体流中去除污染物，可以将几种类型的金属前体引入到高度有序的中孔分子筛（例如SBA-15）上，而不会在孔结构内产生堵塞作用。 从吸附能力和流体速度来看，镧和铝是最有利的掺入金属。 浸渍的镧SBA-15也具有非常强的砷选择性，因为其吸附能力也不会劣化，即使其它任何阴离子物质如硫酸盐和硝酸盐与任何砷一起在流体中发现高浓度。 因此，这些混合材料在POE / POU应用中具有许多优点，其中尤其是由于其快速和高吸附能力，以及其高选择性的砷从流体流中去除。
